I think Ive had my hand in both lol XD I was a bully and was bullied.
I was bullied alot in school for being the "chubby girl" and because that i used to bully others to make myself feel better. You know so i can look in the mirror in the morning and not want to think i had nothing to live for. After awhile i found i was not as fat as people said i was or even made me feel i was. Not only that but After many trips to the councilor's office for my bullying he figured out that I was only acting on my own insincerity. Even tho it's embarrassing to say he used to make me look in a mirror and tell myself i was beautiful just the way i was over and over. After awhile i did feel better and i actually started to believe i was beautiful lol For a very long time every time i saw myself in a mirror i would repeat those words. "I am beautiful just the way I am." lol Kinda silly I know.
but after that I really didnt take bullying from other people. I would brush it off. Because i liked myself and that's all that ever mattered to me.
